I am trying to install the Elastic Cloud on Kubernetes (ECK) Kubernetes operator with the all-in-one.yaml file, as per the tutorial: https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-install-all-in-one.html But I am getting an error:

Error from server: error when creating "https://download.elastic.co/downloads/eck/1.3.1/all-in-one.yaml": the server responded with the status code 413 but did not return more information (post customresourcedefinitions.apiextensions.k8s.io)

I am a bit lost as to how to proceed solving this issue...

Command:

kubectl apply -f https://download.elastic.co/downloads/eck/1.3.1/all-in-one.yaml  --insecure-skip-tls-verify

UPDATE 1:

Running the command (with windows powershell):

curl https://download.elastic.co/downloads/eck/1.3.1/all-in-one.yaml | kubectl apply  --insecure-skip-tls-verify -f-

I get:

error: error parsing STDIN: error converting YAML to JSON: yaml: line 7: mapping values are not allowed in this context
